IMPROVEMENT IN APPARATUS FOR OPERATING FANS.

Specication forming part of Letters Patent No. 116,788, dated July 4,1871.

To all rwhom it may concern Be it known that I, WILLIAM M. BRETON, ofBaltimore, of the county of Baltimore and State of Maryland, haveinvented a new and Improved Apparatus for Operating Fans; and I dohereby declare the following to be a full, clear, and exact descriptionof the same, reference being had to the accompanying drawing making apart of this specification, in which- Figure 1 is a side, and Fig. 2 afront elevation.

This invention consists in an improvement in the class of fans which isknown as Automatic, and is commonly applied to tables of sewingmachinesand the like, in such a manner as to be vibrated by means of a cordconnecting with a treadle. 'lhe invention consists in the construetionof the device for holding the fan, which may be, and preferably is, ofthe ordinary kind; this holder is so constructed, and is so providedwith elastic holding devices, as to adapt it to various sizes of fans.It is also provided with a series of hooks on its under side to permitthe adjustment ofthe treadle-cord, corresponding to the size of fan theforce necessary to operate it, and other conditions it is unnecessary tospecify.

. I will now proceed to describe this device, in connection with othersnecessary to complete the apparatus.

Referring to the drawing, a is a clamp provided with a set-screw, I), sothat it may be attached to a table, c. d is a standard extending upwardfrom the top of the clamp. e e are prongs secured to the upper end ofthestandard, between which prongs is pivoted a fan-holder, j', the samebeing a bar grooved lengthwise of its upper side for the reception of afan-holder, g, and provided with elastic receivers h to hold fan-handlesof various sizes. The holder is provided with hooks along its mider sideto allow of shifting the point of attachment of the treadle-cord, so asto vary the throw of the fan, or for other plnposes. 'i are fingersextending from opposite sides of the standard d. j is a springconnecting an eye, h, set in the lower side ofthe fan-holder f, with oneof the fingers i. l is a cord connecting the upper end of thefan-holderf with a treadle m supposed to be placed upon the iioor in aconvenient position to be worked by a person sitting at the tableopposite the fan. The working of the treadle draws the fan downward andspring j draws it upward. 'lwo iingers, t', are employed, in order that,when the fan-holder is turned the other way in the prongs e, as it issometimes desirable, there may be on the same side as the spring j ameans of attaching it to the standard d. One of the prongs e is extendedas shown at e1, and turned over as shown at e2, in order that the springj may be attached to it above the fanholder, if preferred. Thetreadle-board is hinged in a recess formed in a block, and shaped so asto conform more or less to the shape of the foot. This block may beplaced in any convenient position on the floor, and forms an independentsupport for the treadle while protecting it from external injury. Y

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. In an automatic-fan apparatus, the holder i f provided with theelastic receivers hh, and shaped as and for the purpose specified. 2.The treadle-board, hinged in a recess formed in a block which isdetached or disconnected from other parts of the apparatus, asspeciiied.

p To the above specification of my invention I have signed my hand this6th day of June, A. D. 1871.
